Value Collection SC2082116 Countersink 82 Degree 6 Flute

Product Description

The VALUE COLLECTION SC2082116 is a single-end, 6-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel with a bright uncoated finish, it delivers clean, accurate countersunk seats for flat-head fasteners. The 82-degree included angle — a standard for inch-series flat-head screws — is machined at a 41-degree centerline angle. The straight cylindrical shank measures 0.75 inches in diameter and 1.625 inches in length, fitting standard drill press and mill collet setups. The 1.25-inch head diameter allows coverage of common hole sizes encountered in sheet metal, structural, and general machining work. No pilot is included. Weight is 0.06 pounds.

This countersink suits production and job-shop environments where consistent 82-degree countersunk finishes are required on metal workpieces. It is appropriate for use in manual drill presses, CNC machining centers, and milling machines with a compatible straight-shank collet or chuck. Machinists, tool-and-die workers, and fabricators working with inch-series flat-head screws and rivets will find the 6-flute geometry advantageous for reducing chatter and producing smooth surface finishes at the countersink seat.

Key Features

• 82-degree included angle matches the standard for inch-series flat-head fasteners
• 6-flute design reduces chatter and improves surface finish quality at the countersink seat
• High-speed steel construction provides durability across common metalworking materials
• Straight cylindrical shank at 0.75 inches diameter fits standard collets and drill chucks
• Bright uncoated finish — no additional coating to affect dimensional accuracy
• Single-end, no-pilot configuration for direct setup without a center guide

Compatibility

Designed as an OEM-style replacement or standard countersink for use with drill presses, CNC mills, or milling machines accepting a 0.75-inch straight cylindrical shank collet or chuck.

Installation Notes

Installation is performed by machinists or tool-and-die professionals. Secure the straight cylindrical shank firmly in a compatible collet or drill chuck before use. Ensure the machine spindle is fully stopped and locked before changing or inspecting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
